Hi welcome to YT!!! If the vet says its ok to hold off on the vaccinations then I'm sure its fine but I would definitely take him for his initial check-up. They'll be able to give him a clean bill of health and then you won't have to worry, I just wouldn't let him walk on the floor of Petsmart or places where other dogs have gone until he gets his shots since he's susceptible to all sorts of things right now. Congrats on your new puppy!! He's a cutie!!!
